Risk of injury. Skin or eye injuries may result when handling hot or glowing objects.

k of injury. Skin or eye
injuries may result when
handling hot or glowing objects.

Wear protective gloves,
protective clothing and safety
glasses, if necessary.

Risk of injury

Contact with hot or glowing objects without suitable
protective clothing causes severe burns to skin and eyes.

When glowing objects come into contact with water, they
produce hot steam or cause the water to splash, which can
cause serious burns to skin or eyes.

If hot or glowing objects come into contact with unprotected
skin or eyes, they can cause serious and even permanent
injuries.

li)

There is a risk of fire when glowing objects come into
contact with combustible material.

Safety precautions/instructions

+ Wear protective clothing, safety glasses and heat-
resistant gloves.

+ Only transport hot or glowing objects with suitable aids.
+ Avoid the formation of sparks and contact with

combustible material when handling glowing objects.
First aid measures

+ Treat affected areas of skin with plenty of cold water
and cover with sterile dressings.

+ Consult a physician immediately.

Secure vehicle to prevent it from
starting off by itself. Wear
closed and snug-fitting work
clothes. Do not touch hot or
rotating parts.

Potential risks

Risk of accident

Caused by the vehicle starting off by itself during the
starting procedure

(e.g. during compression test) due to engaged gear or
with the engine running and vehicles with automatic
transmission due to selector lever position "P" or

“N" not being engaged (except for vehicles that do not
have selector lever position "P")
Risk of injury

Severe injuries can be caused by freely rotating parts in
the area of the running engine.

Because the engine heats up when operating, serious

burns can be caused by touching unshielded parts.

Safety instructions/precautions

+ In general, only work on a running engine when it is
absolutely necessary.

+ Apply parking brake before starting the engine.

+ The vehicle is to be secured against moving forwards or
backwards.

+ The person performing tests on a vehicle with the
engine running must sit in the driver's seat to be able to
prevent the vehicle from moving.

It is not permitted for persons to be in the danger zone
in front of or behind the vehicle while tests are being
performed.

Shift the gearshift lever to neutral on vehicles with
manual transmission.

On vehicles with automatic transmission, move selector
lever into position "P" or "N" (except for vehicles that
do not have selector lever position "P").

On vehicles that do not have selector lever position
the selector lever is to be secured against
unauthorized access.

Wear closed and snug-fitting work clothes.
Remove all jewelry such as necklaces, rings, etc.
Wear suitable head wear to cover long hair.

Before commencing any work on the running engine,
familiarize yourself with the location of potentially hot
parts.

When carrying out work when starting the engine or
when the engine is running, do not touch any hot or
rotating parts.

Use the exhaust extraction system.

First aid measures in the event of burns

+ Do not rub the skin areas affected; rinse with plenty of
cold water and cover skin with sterile dressings.

Consult a physician immediately.

Risk of injury. Moving parts can pinch, crush or, in extreme cases even sever extremities.

Risk of injury. Moving parts
can pinch, crush or, in extreme
cases even sever extremities.

No parts of the body or limbs QWaming

should be within the operating
area of mechanical components
when moving components.

Risk of injury

When working on components that can be moved either by
hand, by means of electric motors, or hydraulically/
pneumatically via a connecting mechanism, serious injuries
can occur due to body parts being cut, pinched or crushed.

Safety instructions/precautions
+ Monitor hazard area.

Secure the operating area of mechanical components
against interference when parts are in motion.

Never touch the mechanism of a component while it is
being actuated by electric motors via the diagnosis or by
direct actuation (terminal 30).

Choose a test cable of sufficient length.

Risk of burn injuries and

when handling AdBlue®. Risk
of poisoning caused by
swallowing AdBlue®

Risk of injury to skin and eyes

Pour AdBlue® into suitable Awaming

containers only. Wait until the
pressure is released before
starting any work on the
exhaust aftertreatment system.

Potential risks

Risk of burn injuries and scalding

The AdBlue® lines and all components attached to them
are under pressure during operation and remain so after
the engine is switched off and may be hot. There is a risk of
burn injuries. There is a risk of scalding caused by
escaping hot AdBlue® when the line system is opened.

Risk of injury

There is a risk of skin irritation and eye damage on contact
with AdBlue®.

Risk of poisoning

There is a risk of poisoning if AdBlue® is swallowed.

Rules of conduct

* On vehicles with electrical delivery pump, the AdBlue®
is pumped from the line back into the AdBlue® tank
after the engine is switched off.

Safety precautions for handling removed parts and
working under the vehicle

+ Wear suitable protective gloves
+ Wear protective clothing
+ Wear safety glasses

First aid measures

Contact with skin: Wash the affected skin areas with plenty
of clean water. Change wetted clothing as quickly as
possible.

* On vehicles with a compressed air system, individual
lines are flushed with compressed air after the engine is
switched off. The engine must therefore be switched off
for at least 5 minutes before work on the exhaust
aftertreatment system may begin.

+ Open connections and plugs on the system components
slowly. Cover the connecting point with rags when
opening.

Only pour AdBlue® into marked containers specially
designated for the purpose. Do not pour AdBlue® into
drinking containers

+ Wipe up any AdBlue® spills immediately as there is a
high risk of someone slipping.

Contact with eyes: In the event of contact with eyes,
immediately rinse eyes thoroughly with plenty of clear
water; contact an eye doctor if necessary.

Ingestion: rinse mouth with clean water and drink large
quantities of water. Immediately seek medical assistance.

Firefighting measures

AdBlue® is not combustible. NH3 (ammonia) can be
released in the event of fire, causing a risk of poisoning.
Firefighting measures must therefore be suited to the
surroundings.
